Boys must have played with laser pointers when they were young, and they have been scolded a lot about it, right? Because the laser played when they were young is harmful to the eyes, many parents will mostly prohibit children from touching this dangerous "toy".
Now, Xiaomi has a safety laser small toy that uses a standard class II laser but was bought by rice noodles, and the amount of crowdfunding exceeded 4600000, it seems that the children of that year still loved to play.
Coincidentally, I was also one of the children who had not been addicted to play, and I took the opportunity to buy a tape measure for the family to change into a small monkey intelligent laser rangefinder, and this time I took a good look at whether the small toys of that year could still arouse the heart of the old man.
Fast and accurate
Old rice noodles all know that the products that can be crowdfunded by Xiaomi must have been strictly screened, so the quality of the products that have been crowdfunded by Xiaomi is generally good.
The xiaomi monkey intelligent laser rangefinder I am holding in my hand is also the same, the design is very unique, and a large color change ring is opened on the black matte texture fuselage for easy carrying, and it can be carried on the finger.
The speed of ranging is also very fast, as long as the switch is pressed twice, the laser injection and then retracted can display the measurement data within 1 second, and more strictly speaking, it can complete this set of emission-calibration-secondary emission-display data process in 0.2 seconds.
And the displayed value is accurate to the millimeter level, compared to the tape measure, the reading of the intelligent laser rangefinder is clear at a glance, without counting in the centimeter range one by one.
Compare its accuracy again, just to set the sofa cover and table cloth at home, use the rangefinder and tape measure to compare the difference in measurement values. When measuring the height of the handrail, the rangefinder shows 0.542 meters, while the tape measure measures the height of 0.54 meters, and the difference in value is two millimeters.
However, this is normal, and the error of two millimeters is within the acceptable range, because ordinary household measuring instruments will basically have a slight error and will not affect my subsequent custom sofa cover. Moreover, when measuring twice, a slight difference in the position of the hand placement will also make a difference in the measurement results of the two.
The accuracy of the rangefinder was then tested again at the length of the table, and this time the measurement result was 0.992 meters, the same as the measurement value of the tape measure.
After many repeated tests, the measurement results of the rangefinder and the value measured by the tape measure are always kept within the range of ±2mm, and most of the time the value of the tape measure is consistent. Because it is a laser ranging, it is certainly not as stable as the tape measure ranging effect, but it is always stable within the error of two millimeters, which is already very good for the laser rangefinder.
Moreover, the little monkey laser rangefinder can also record each measurement data stably in the background after fast ranging while quickly measuring the distance, which is convenient for quickly establishing a floor plan in the APP in the later stage.
summary
Experience down, the little monkey intelligent laser rangefinder did not let me find the joy of childhood, but it greatly facilitated my life, a small rangefinder in a few minutes can achieve a tape measure half a day's workload. From a toy to a common tool for old men to return to the family, perhaps this is the role it should play the most. Double 11 is approaching, interested can go to Xiaomi to see, very affordable.
